What did Chargaff discover while studying bases in the DNA of organisms?

Biology

swat323 years ago
5 0
Chargaff found out that t<span>he ratios of thymine and adenine were equal and the ratios of guanine and cytosine were equal. He then created the Chargaff's rule states that double stranded DNA has a 1:1 ratio between pyrimidine and purine bases. With this, </span><span>amount of guanine bases is equal to cytosine bases while the amount of adenine bases is equal to thymine bases.</span>

The diagram below shows some of the steps in protein synthesis.
Zinaida [17]

Answer:

According to the diagram shown, the section of DNA used to make the mRNA strand is known as a gene (option 2).

Explanation:

Gene consists of a DNA fragment that codes for the synthesis of a specific protein that defines the structural or functional trait of a living being.

When DNA is transcribed into mRNA, each section of transcribed DNA is part of a gene. The information travels to ribosomes in the cytoplasm where protein synthesis occurs.

A complete DNA molecule forms a chromosome, which contains the genes with information to define specific traits of a species.

The other options are not correct because:

<em>     1.Carbohydrate is a biomolecule that is not involved in the genetic process. </em>

<em>     3. Ribosome is where protein synthesis occurs. </em>

<em>     4. Chromosome is the complete DNA molecule.</em>

Between 1957 and 1961, thousands of expectant women in 30 different nations ingested a common antinausea drug of the time known
Elza [17]

Answer:

A study of <u>those newborn babies</u>

Explanation:  

Studying the infants from these pregnant women lead the researchers to find out that this drug interfered with the process of limb formation if the pregnant woman had taken this drug anytime during the 26 days critical for limb formation and development. In this way, it makes for an instance where nurture had disrupted nature.

Why is the resting membrane potential (Vm) approximately - 70 mV for most cells? Most cells contain a large concentration of Cl-
Yuki888 [10]

Answer:

Option (4).

Explanation:

Cell membrane potential may be defined as the difference in the electric potential between inside and outside of the cell. This potential is important for the action potential.

The resting membrane potential of the cell is -70mV. This membrane potential is maintained by the potassium ions of the cell. The cell membrane are almost 40 times more permeable to potassium ions than sodium ions and makes the cell membrane potential negative.

Thus, the correct answer is option (4).

A star turns matter into energy in the process of
yarga [219]
A star is a fusion reactor. Under enormous pressure, resulting from gravity, light nuclei of gases such as hydrogen merge to form helium, and since this process releases energy, the start begins to radiate the excess energy. Later on, helium fusion produces heavier elements, and so on.
